Bombelli, in his Algebra, published in 1572, was to produce a proper set of rules for manipulating these 'complex numbers'. Descartes in 1637 says that one can 'imagine' for every equation of degree n, n roots but these imagined roots do not correspond to any real quantity.

Distinct variable provisos, which accompany certain axioms and are inherited by theorems, ... [It may seem peculiar to substitute a + sign for a variable, because you wouldn't do that in high-school algebra. We can do this because the variables represent arbitrary objects called "classes," not just numbers.
